Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing communication systems struggle to maintain line of sight communication in hostile environments due to obstacles and dynamic threats, making it difficult to deploy repeaters effectively for real-time communication between forward agents and command personnel.

Innovation Solution

A method involving a maneuverable drone that deposits a series of independently deployable repeaters to establish a mesh network, allowing wireless communication between a base station and a forward agent, even in dynamic and obstructed environments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If repeaters are pre-installed between base station and forward agent, then communication coverage is improved, but deployment flexibility deteriorates because precise threat location is unknown in advance

Engineering Contradiction:

Improvecommunication coverageVSAvoiddeployment flexibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system performs preliminary actions by pre-positioning repeaters in potential threat zones before the actual threat is identified. These repeaters remain dormant until activated by electromagnetic signal detection, allowing the system to prepare communication infrastructure in advance without committing to specific locations.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The repeater network transitions from a static pre-installed configuration to a dynamic system that activates and repositions repeaters based on real-time electromagnetic signal detection. The base station can remotely activate specific repeaters and adjust their operational status according to detected threat locations.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If repeaters are dynamically installed in real time during advance towards threat, then communication adaptability is improved, but weight penalty and limited maneuverability worsen for robot or drone forward agents

Engineering Contradiction:

Improvecommunication adaptabilityVSAvoidweight penalty

Core Design Contradiction:

Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The system introduces a separate repeater deployment mechanism independent of the forward agent. Unmanned aerial vehicles or ground vehicles deploy repeaters along advance paths, allowing the forward agent to maintain lightweight design while communication infrastructure is established by intermediary deployment platforms.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The communication system is segmented into two independent components: the forward agent and the repeater network. This separation allows the forward agent to remain lightweight while the repeater network provides the necessary communication infrastructure through independent deployment platforms.

Inventive Principle:

Principle #1Segmentation

3Reliability

If wired systems are used for forward agent communication, then communication reliability is improved, but ease of operation deteriorates due to wire cutting sabotage and maneuverability constraints

Engineering Contradiction:

Improvecommunication reliabilityVSAvoidmaneuverability

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system replaces mechanical wired connections with wireless electromagnetic communication. Repeaters establish wireless relay channels between the forward agent and base station, eliminating physical wires that could be cut or interfere with agent maneuverability while maintaining communication reliability through the mesh network.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Reliability

If multiple robots are used as radio relays, then communication coverage is improved, but device complexity increases and deployment becomes cumbersome in congested environments

Engineering Contradiction:

Improvecommunication coverageVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system employs multi-functional unmanned platforms that can perform both forward agent duties and repeater deployment. These universal platforms reduce overall system complexity by consolidating functions that would otherwise require separate specialized robots, while maintaining comprehensive communication coverage.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A portable communication system for use in hostile and unknown environments. The system has a base station for control by an operator. The base station dispatches one or more unmanned drones into the hostile environment, where a forward agent, such a robot or investigative person can approach a suspected threat. Each drone has a payload of repeaters to be delivered as necessary to maintain line of sight communication from the forward agent back to the base station. Once delivered, the repeaters are mobile and can autonomously reposition to maintain or optimize line of sight communication. Communications from the forward agent back to the base station are then interpreted and analyzed for further action.
